"I'm scared of the dark now. I can't go out by myself and I can't sit in the car without all the doors being locked."

Det Sgt Jenny Farman is asking anyone who knows the man in the CCTV footage to come forward.

The man we would like to speak to about the assault is wearing a dark coloured shirt with short sleeves and light coloured trousers.
